' teaser CRUMB BRUSH AND TRAY.

App1ication filed September 29, 1924, Serial No. 740,619, and in Great Britain October 3, 1923.

T his invention has for its object to provide a crumb brush and tray combined in a single unit and so arranged as to be capable of I operation by a single hand. 5 The improved device according to the present invention'comprises a crumb tray, a rotary brush of tapered or conical form mounted thereon justinadvance of the lead: ing edge of the tray and having a small 10 friction wheel mounted at the small end thereof and engaging the surface to be swept,

'the said wheel effecting the rotation of the brush at a peripheral speed greater than ,the speed at which the tray as a whole is 15 moved along the surface to be swept.

In order to enable the invention to be clearly understood reference is made to the accompanying drawings, in which Fig. 1 is a front elevation, and Fig. 2 a cross sec- 20 tion of a crumb brush and tray constructed according to this invention.

Referring to the drawings the rotary brush 1 is formed of a number of bristles 2 in inter-engagement with a plurality of twisted wires 3 which form a centre or axis thereto and is a well known construction of wire centred brush. It will be evident "however that the brush may be constructed in any other convenient manner. The rotary brush 1 is mounted to turn in bearings attached to the crumb tray 5, which is shown. with a cover portion 6, and a handle 6. At the end of the tray remote from the. handle an opening 6 is provided for the discharge of the crumbs. 1

The brush 1 is so positioned with respect to the tray 5 as to contact with the surface to be swept at a point just in advance of the leading edge of the tray when the device is held in the normal position for use.

In order that the peripheral speed of the brush 1 may be greater'than the speed at which the tray 5 is moved over the surface to be swept, the brush 1 is of tapered or conical form as shown and at its smaller end is prol5 vided with a friction wheel 7, which when the device is moved over the surface to be swept by means of the handle'6" engages said surface and brings about the rotation of the brush.

As for the greater part of its length, the diameter of the brush 1 exceeds that of the friction wheel 7, the underside oi contacting surface of the brush will move in a rearward direction at a slightly greater speed than the movement of the tray 5 as a whole in a for ward direction. 1

A crumb brush and tray comprising a crumb tray having a cover portion with a discharge opening at one end, ahandle attached to the other end of the tray, a rotary brush of tapered form mounted on the tray immediately in advance of the leading edge ofthe tray with its smaller end adjacent to the handle and a small friction wheel mounted at the small end of the brush and adapted to engage the surface to be swept,

the said'wheel effecting the rotationof the 1 brush ata peripheral speed greater than the speed at which the tray as a whole is moved 3 along the surface to be swept and by its an rangement on the small end of the brush closeto the handle enabling the pressure of the hand holding the applianceto be utilized eflect-ively for maintaining frictional engagement between the wheel and the surface to be swept.

In testimony whereof he has affixed his signature. i 1
